Ionizing radiation causes irreversible skin damage, with single doses leading to acute injury and hair graying, and fractional doses causing more severe long-term tissue damage.

A new painless method to collect hair follicles helps study DNA damage and aging.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

Bcl-2 overexpression protects against UVB damage but worsens hair loss from chemotherapy.

Gamma-rays exposure during the resting phase of hair growth can damage hair regeneration and color in mice.

Targeting the protein Caveolin-1 might help treat a type of scarring hair loss called Frontal Fibrosing Alopecia.

Regenerative therapies show promise for treating vitiligo and alopecia areata.

Hair follicles are essential for skin health, aiding in hair growth, wound healing, and immune function.

Human hair follicles may provide a noninvasive way to diagnose diseases and have potential in regenerative medicine.

SOX2 is crucial for skin cell function and hair growth, and it plays a role in skin cancer and wound healing.

Overexpressing ornithine decarboxylase and v-Ha-ras in keratinocytes leads to invasiveness and malignancy.

Minoxidil affects cell growth in two ways: low doses increase growth, while high doses slow it down and can be toxic.

Sebaceous glands play a key role in skin health, immunity, and various skin diseases.

Improved understanding of stem cell mechanisms can enhance skin tissue engineering.

Hair and skin healing involve complex cell interactions controlled by specific molecules and pathways, and hair follicle cells can help repair skin wounds.

ODC overexpression in hair cells increases tumor growth by reducing Notch signaling.

Lichen planopilaris is a chronic, scarring hair loss condition with no definitive cure, requiring accurate diagnosis and treatment to manage symptoms.
